An Intelligent Multiattribute Decision-Support Framework Based on Parameterization of Neutrosophic Hypersoft Set

Hypersoft set is a novel area of interest which is able to tackle the real-world scenarios where classification of parameters into their respective sub-parametric values in the form of overlapping sets is mandatory. It employs a new approximate mapping which considers such sets in the form of sub-parametric tuples as its domain. The existing soft set-like structures are insufficient to tackle such kind of situations. This research intends to establish a novel concept of parameterization of fuzzy set under hypersoft set environment with uncertain components of intuitionistic fuzzy set and neutrosophic set. Two novel structures, i.e., fuzzy parameterized intuitionistic fuzzy hypersoft set (fpifhs-set) and fuzzy parameterized neutrosophic hypersoft set (fpnhs-set), are developed by employing algebraic techniques like theoretic, analytical, pictorial, and algorithmic techniques. After characterizing the elementary properties and set-theoretic operations of fpifhs-set and fpnhs-set, two novel algorithms are proposed to solve real-life decision-making COVID-19 problem. The results of both algorithms are compared with related already established models through certain evaluating features to judge the advantageous aspects of the proposed study. The generalization of the proposed models is discussed by describing some of their particular cases.


Introduction
e conventional logic is not always significant in real-life state of affairs, where the accessible information is unclear or indefinite. To cope with such sort of circumstances, a specific class of sets recognized as fuzzy set (f-set) (initiated by Zadeh [1]) is regarded as apt. In such set, a belonging grade within [0, 1] is assigned to each element of the initial universe. Nevertheless, to manage more complex and uncertain real-life situations, f-set was found incapable, and therefore Atanassov [2] established a novel model, i.e., intuitionistic fuzzy set (if-set) which is more effective in tackling vagueness of data. It assigns belonging and nonbelonging grades to each element of the initial universe subject to the condition that their sum lies within [0, 1].
Moreover, if-sets are proficient at emulating the available information more precisely and rationally. Many researchers made contributions regarding the extensions of f-sets and if-sets, but the contributions of Deli and Keleş [3], Mahmood et al. [4],Ünver et al. [5], and Wang and Garg [6] are more significant. ey introduced novel extensions of if-sets and applied them in real-world problems through algorithm-based decision-making techniques. Both f-sets and if-sets were observed to be incapable of considering the grade of indeterminacy, so neutrosophic set (n-set) was instigated by Smarandache [7] to deal with such kind of limitations. e n-set is more proficient at preserving the impreciseness in the contents of perceived data and may assist rough reasoning behavior meticulously. Although the expressive capacity of n-set is higher than that of the conventional f-set and if-set due to the consideration of a neutral grade, they have reasonably higher computational complication over f-set and if-set. e above described structures showed some drawbacks with respect to the consideration of parameterization tool. To manage such insufficiency, Molodtsov [8] developed soft set (s-set) as a new mathematical tool. In s-set, an approximate mapping is used to map a set of parameters to power set of universe. In order to enhance the applicability of s-set in real-world uncertain scenarios, some of its hybridized structures like fuzzy soft set (fs-set) [9,10], intuitionistic fuzzy soft set (ifs-set) [11,12], and neutrosophic soft set (ns-set) [13] were developed. Ali et al. [14], Li [15], Maji et al. [16], Pei and Miao [17], and Sezgin and Atagün [18] discussed the rudiments of s-set with numerical examples. Babitha and Sunil [19,20] introduced the concept of relations, functions, and orders under soft set environment. Broumi et al. [21] and Deli [22] developed hybridized structures of n-set with s-set with interval settings. ey described some of their rudimentary properties and applied different methods for their implementation in certain cases.
In various real-life decision-making situations, it is observed that nonoverlapping sets having sub-parametric values corresponding to parameters are required to be considered, but the s-set and its hybrids are not projected for such situations. erefore, Smarandache [23] presented the notion of hypersoft set (hs-set) which is capable of handling such situations by using a new approximate mapping having multiargument domain. In order to utilize hs-set in other fields of study, its various basic properties, relations, and matrices have been investigated in [24] with the help of supporting examples. Debnath [25] discussed the decision-making application based on weightage operators of fuzzy hypersoft set. Deli [26] developed a novel hybrid of hs-set called "neutrosophic valued n-attribute neutrosophic hypersoft set" which generalizes most of the existing fuzzy set-like structures for dealing with uncertainty, vagueness, and indeterminacy. Kamacı and Saqlain [27] discussed the validity of hs-set for the entitlement of multidecisive opinions under expert set environment. Martin and Smarandache [28,29] discussed the hybridization of hypersoft set with plithogenic set and discussed its applications. Rahman et al. [30][31][32][33] studied various notional properties of complex set, convex cum concave sets, and parameterization by using the environment of hs-set.
ey also solved realworld decision-making problems with the help of algorithms based on such hybrids. Saeed et al. [34][35][36] extended the concept by introducing the mappings and graphs of hs-set with indeterminate settings and discussed its implementation in product selection and medical science. Saqlain et al. [37,38] discussed aggregation operators, distance, and similarity measures of neutrosophic hypersoft sets with application in decision-making. Zulqarnain et al. [39] investigated generalized aggregate operators for neutrosophic hypersoft sets with some results.

Research Gap and Motivation
(1) e phrase "parameterization of fuzzy set" is actually meant for dispensing the fuzzy value to each attribute/subattribute in the domain of single-argument/ multiargument approximate function (maa-function).
(2) Many researchers discussed the parameterization of fuzzy set-like structures under soft set environment with fuzzy set-like settings. e literature review of most relevant models is presented in Table 1. It can be observed easily that the abovementioned models focused on a single set of attributes and used ordinary soft approximate mapping to study the parameterized nature of parametric domain. ey are incapable of dealing with situations having compulsion partitioning of attributes into their respective attribute-valued nonoverlapping sets. (3) e incapability of soft set-like models leads to the demand for new structure; therefore, hs-set is initiated to manage such situations. As hs-set emphasizes deep observation of attributes, hs-set can be considered as flexible and reliable model to have unbiased decision-support system. In Figure 1, the difference between s-set and hs-set is presented with the help of an example for product selection through decisionmaking. (4) Motivated by the above-mentioned literature in general and [43,44,[47][48][49][50] in specific, we construct novel structures of fuzzy parameterized intuitionistic fuzzy hypersoft set (fpifhs-set) and fuzzy parameterized neutrosophic hypersoft set (fpnhs-set) and characterize them with the help of algorithm-based decision-support systems.

Main Contributions.
Main contributions of this research are given below: (1) e structures like those in [43,44,[47][48][49][50] are made capable with the entitlement of maa-function by characterizing fpifhs-sets and fpnhs-sets. (2) e situations with sub-parametric-valued sets are managed for the environments of if-set and n-set by using fpifhs-sets and fpnhs-sets, (3) Some essential rudiments, i.e., properties, elementary laws, and aggregation operations of fpifhs-set and fpnhs-set are investigated. (4) Two algorithms based on fpifhs-set and fpnhs-set are proposed to deal with daily-life decision-making problems having uncertain data/information in COVID-19 scenario. (5) In order to judge the distinction of this research, the computed algorithm-based results are compared with most relevant models by considering suitable evaluating indicators.

In order to observe the advantageous aspect of the proposed study, a comparison is presented with some existing relevant models in Section 5, and Section 6 presents the discussion on generalization and merits of proposed work. e paper is summarized with future directions in the last section.

Preliminaries
is portion of the paper presents some elementary terms and definitions by reviewing the existing literature for clear understanding of the proposed study. roughout the rest of the paper, the symbols U, P(U), and I denote universe of discourse, power set of U, and closed unit interval. Furthermore, F (U), IF(U), and N(U) denote the collection of f-sets, if-sets, and n-sets over U, respectively. In 1965, Zadeh [1] initiated the concept of fuzzy set as a generalization of classical set (crisp set) to deal with uncertain nature of data. is set employs a membership function which maps set of objects (alternatives) to unit closed interval.

Definition 1 [1]. A fuzzy set P is defined as such that T P : U ⟶ I where T P (u) represents the membership grade of u ∈ P.
Fuzzy set emphasizes degree of membership only for dealing with uncertain scenarios, but there are many situations where it is necessary to consider nonmembership degree; therefore, into adequate fuzzy set with such situation, Atanassov [2] introduced intuitionistic fuzzy set as a generalization of fuzzy set. It provides due status to both membership and nonmembership degrees of an alternative.
An intuitionistic fuzzy set Q is defined as such that T Q : U ⟶ I and F Q : U ⟶ I, where T Q (u) and F Q (u) denote the membership and nonmembership grades of u ∈ U subject to the condition that Both fuzzy set and intuitionistic fuzzy set are insufficient to tackle the various uncertain scenarios where the consideration of indeterminate grades is necessary. In order to manage such situations, Smarandache [7] characterized neutrosophic set which not only considers membership and nonmembership grades but also provides due status to degree of indeterminacy of an alternative.
A neutrosophic set R is defined as such that T R (u), I R (u), F R (u): U ⟶ ( − 0, 1 + ),where T R (u), I R (u), and F R (u) represent the grades of membership, indeterminacy, and nonmembership of u ∈ U subject to the condition that Fuzzy set, intuitionistic fuzzy set, and neutrosophic set depict some kind of insufficiency regarding the consideration of parameterization tool. In order to manage this limitation, Molodtsov [8] developed soft set as a new mathematical tool to tackle uncertainties and vagueness in the data.
A soft set over U is a pair (F S , G), where F S : G ⟶ P(U) and G ⊆ E (a set of parameters).
More details on soft set and its operations can be seen in [10,16]. In many real-world scenarios, the classification of attributes into sub-attributive values in the form of sets is necessary. e existing concept of soft set is not sufficient and is incompatible with such scenarios, so Smarandache [23] introduced hypersoft sets to address the insufficiency of soft set and to handle the situations with multiargument approximate function (MAAF). For the sake of proper use of hypersoft set under uncertain environments, the hybrids of s-sets like fs-sets, ifs-sets, and ns-sets are further modified for hypersoft set environment so the following novel structures are conceptualized.
A hypersoft set (W, H) is called fuzzy hypersoft set, intuitionistic fuzzy hypersoft set, and neutrosophic hypersoft set if P(U) in W: H ⟶ P(U) is replaced with F (U), IF(U), and N(U), respectively.
For more details on hypersoft set and its operations, please see [23,24].
Before presenting main results, first necessity of the proposed study is discussed. In various daily-world scenarios like product selection, supplier selection, and medical diagnosis, the decision-makers face the following problems: (1) e chosen parameters (attributes) need to be further partitioned into their respective attribute-valued disjoint sets. In order to manage all above problems collectively, parameterization of hypersoft set with fuzzy setting is required under intuitionistic fuzzy set and neutrosophic set environments which lead to the demand for the proposed study.

Fuzzy Parameterized Intuitionistic Fuzzy Hypersoft Set (fpifhs-Set) with Application
In various real-world decision-making scenarios, the decision-makers are uncertain about the nature of selected parameters under hs-set environment with approximate elements having intuitionistic fuzzy values. Such type of parameters is known as fuzzy parameters, and such scenarios are tackled with the help of fpifhs-set. e methodology of the proposed study is explained in Figure 2. In this section, firstly theory of fpifhs-set is constructed, and then decision-making problem is discussed with the help of proposed algorithm. 4 Computational Intelligence and Neuroscience where is known as approximate function of fpifhs-set.

Problem Scenario.
Hand sanitizer is a fluid or gel that is utilized to kill germs on the hands. As per the World Health Organization (WHO), excellent sterilization and actual detachment are simply the most ideal approaches to rescue the individuals from COVID-19 in the ebb and Computational Intelligence and Neuroscience flow illness circumstance.
is infection is communicated by reaching somebody who is debilitated. We cannot be excessively cautious with this infection on the off chance that we do not isolate ourselves totally. Accordingly, great disinfection can be the best way to guard us against the infection. WHO suggests alcohol-based hand sanitizers (ABH-sanitizers) for eliminating the novel corona virus. ABH-sanitizers prevent germ proteins, like microscopic organisms and infections, from working ordinarily.
ere are two kinds of formulations (see Figure 5) recommended by WHO for the production of large quantities of hand sanitizer from chemicals available in developing countries, where commercial hand sanitizer may not be available. e interest in hand sanitizers has expanded drastically in light of COVID-19's critical situation. us, discovering Start Input: (1) Consider U as universe of discourse (2) Consider B as set of n parameters (3) Classify n parameters into disjoint parametric-valued sets B 1 , B 2 , B 3 , . . . , B n Construction:  Figure 4: Decision-making algorithm for fpifhs-set. 8 Computational Intelligence and Neuroscience great and powerful hand sanitizers in local markets is troublesome. Because of the expanded interest, inferior quality hand sanitizers have additionally been dispatched. e fundamental objective of this application is to utilize fpifhs-set and fpnhs-set theories to track down a successful sanitizer to stop the spread of COVID-19.

Operational Role of Constituents of ABH-Sanitizers.
It is clear from Figure 5 that ABH-sanitizers have four major constituents that are given below with their brief operation role in sanitation process: (1) Ethanol: It is an organic chemical compound and majorly used in medication as antiseptic, antidote, and medicinal solvent. It is the major constituent of ABH-sanitizers, and it ranges from 70% to 80%(V/V) as an active ingredient. (2) Glycerol: It is a nontoxic viscous liquid having no color, no odor, and sweet taste. It is mildly antimicrobial and antiviral. It prevents skin dryness with its moisturizing properties. It draws moisture up through skin layers and slows or prevents excessive drying and evaporation. It is added to ABH-sanitizers to prevent drying of the skin, and it ranges from 1.35% to 1.45%(V/V) as an active ingredient. (3) Hydrogen peroxide: It is a very pale blue colored chemical compound having viscosity slightly more than water. Usually as a dilute solution (3-6% by weight) in water, it is used as an oxidizer, bleaching agent, and antiseptic for consumer use. It can be used for industrial purposes with high concentrations. It is used in ABH-sanitizers as sterilizer, and it ranges from 0.120% to 0.125%(V/V) as an active ingredient. (4) Distilled water: It is an essential ingredient of ABHsanitizers. It ranges from 15.425 % to 23.425%(V/V) as an active ingredient. It is used as cleansing agent to prevent the interaction of chlorine and other contaminants with the alcohol and other ingredients in the sanitizer.

Statement of the Problem. Professor John is the head of an educational institution.
He is very concerned about the health of the students as well as the faculty members of his institution in view of the current coronary epidemic. He wants to buy good and useful hand sanitizers for his institution, but he is also worried about the nonstandard hand sanitizers available in the market. erefore, he decides to call for bids from different potential suppliers for this purchase to fulfill the departmental official compliances and to avoid any expected loss. Some suppliers are scrutinized by adopting proper procedure already framed by relevant department. For the sake of satisfaction, he constitutes a committee consisting of some staff members with good procurement experience to evaluate the items (hand sanitizers) offered by scrutinized suppliers. e following example elaborates the whole procedure of such evaluation:

With their mutual consensus, the committee members (experts) agreed on a set of parameters after observing various attributes for this evaluation. e finalized evaluating attributes are b 1 manufacturer; b 2 quantity of ethanol (percentage); b 3 quantity of distilled water (percentage); b 4 quantity of glycerol (percentage); and b 5 quantity of hydrogen peroxide (percentage). After observing the opinions of various professionals and other relevant sources on the composition of hand sanitizers, these attributes are further classified into attribute-valued sets which are given as where each q i , i � 1, 2, . . . , 24, is a 5-tuple element. For convenience, take R � q 1 , q 2 , q 3 , q 4 , . . . .., q 16 ⊆ Q.

Fuzzy Parameterized Neutrosophic Hypersoft Set (fpnhs-Set) with Application
fpifhs-set is quite better to tackle real-world decisionmaking scenarios where the decision-makers are uncertain about the nature of selected parameters under hs-set environment with approximate elements having intuitionistic fuzzy values. However, it is still insufficient to manage the situation when approximate elements are needed to be assessed with indeterminacy degree; therefore, this shortcoming demands another structure to deal with these situations. erefore, in this section, the theory of fpnhs-set is developed with the characterization of some of its essential rudiments and decision-support system.

Comparison Analysis
ere are many cases where consideration of attributes only is not sufficient; all available distinct attributes are further partitioned into their respective disjoint attributive sets. Decision-making techniques based on existing soft set-like models are inadequate for such cases. erefore, our proposed models not only emphasize the due status of such partitioning of attributes, but also enable the decisionmakers to deal with daily-life problems with great ease. Tables 8 and 9 present a clear comparison of our proposed models with some existing models under the evaluating indicators MD (membership degree), NMD (nonmembership degree), ID (indeterminacy degree), SAAF (single-Start Input: (1) Consider U as universe of discourse (2) Consider B as set of n parameters (3) Classify n parameters into disjoint parametric-valued sets B 1 , B 2 , B 3 , . . . , B n Construction: argument approximate function), and MAAF (multiargument approximate function). Figure 12 depicts the comparison of reduced fuzzy values obtained from our proposed structures.

Discussion
Decision-makers consistently face a type of uncertainty and the decision taken by overlooking uncertainty might have some degree of tendency. Indeterminacy and uncertainty are both interconnected and interrelated. e proposed work has elaborated (for example, see Figure 12) how the results are affected by the omission or consideration of some uncertain components while dealing with the real-world problems under any decisive system. Two models fpifhs-set and fpnhs-set have been proposed and characterized. e latter one is very useful, flexible, and reliable in dealing with problems having uncertain information and data. e following discussion shows the generalization of fpnhs-set as it fulfills all the characteristics, features, and properties of many existing soft set-like models. In Definition 18:  Figure 9: Decision-making algorithm for fpnhs-set.       [43] fpfs-set ✔ × × ✔ × Deli and Çagman [44] ifps-set ✔ ✔ × ✔ × Joshi et al.

(v) If only set of parameters is considered after omitting G � S 1 × S 2 × S 3 × · · · · ×S n and replacing N(U) with IF(U), then it is called fpifs-set. (vi) If only set of parameters is considered after omitting G � S 1 × S 2 × S 3 × · · · · ×S n and replacing N(U) with F(U), then it is known as fpfs-set. (vii) If A D (g)/g is replaced with g, then it is called nhs-set. (viii) If A D (g)/g is replaced with g, and N(U) is replaced with IF(U), then it is called ifhs-set. (ix) If A D (g)/g is replaced with g, and N(U) is replaced with F (U), then it is called fhs-set.
Similarly, fpnhs-set transforms to s-set by ignoring all uncertain components and considering only set of attributes. From Figure 13, it is obvious that the proposed structure is the most generalized structure satisfying all the main characteristics of existing relevant structures.

Advantages of Proposed
Research. Now, some advantages of the proposed structure (i.e., fpnhs-set) are presented below: (i) e proposed technique took the importance of the concept of parameterization along with the nhs-set for dealing with decision-making problems. e considered parameterized fuzzy degree mirrors the possibility of the existence of the level of acknowledgment and excusal; along these lines, this association has marvelous prospective in the legitimate representation inside the space of computational incursions. (ii) Due to focus on deep observation of parameters and respective attribute-valued sets, the proposed model may assist the decision-makers to have flexible and reliable decisions through decision-making. (iii) It validates all the qualities and properties of the predefined models so it is not irrational to consider it as the generalized version of these models.
e advantage of the proposed structure can easily be judged from Tables 8 and 9. e comparison is evaluated on the basis of two different aspects: (1) Main features discussed in the study (see Table 8).

Conclusion
e key features of this work can be summarized as follows: (1) e fundamental theory of fpifhs-set is developed, and its decision-support system is constructed. A real-world problem (an optimum selection of hand sanitizer) is discussed with the support of the proposed algorithm and decision system of fpifhs-set. (2) e rudiments of fpnhs-set are characterized, and its decision-making based system is developed. A reallife problem (an optimum selection of hand sanitizer) is studied with the help of proposed algorithm and decision system of fpnhs-set. (3) Both proposed models, fpifhs-set and fpnhs-set, are compared professionally via inter-cum-intra-strategy with some existing relevant models in view of important evaluating features. (4) e particular cases of the proposed models fpifhs-set and fpnhs-set are discussed with the generalization of these structures. (5) Although the proposed structure is generalized and reliable for decision-making scenarios, it is flexible due to some limitations; for example, it is inadequate for the situation when the inclusion of nonmembership grade and indeterminate grade in the domain of multiargument approximate function is mandatory. erefore, future work may include the following: (i) e extension of this study to develop intuitionistic fuzzy parameterized neutrosophic hypersoft set and neutrosophic parameterized neutrosophic hypersoft set to tackle the situations having mandatory inclusion of nonmembership grade and indeterminate grade in the domain of multiargument approximate function. (ii) e application of this study to discuss realworld problems using multicriteria decisionmaking approaches like TOPSIS, PROM-ETHEE, and MULTIMORA. (iii) e application of this study to discuss realworld problems (e.g., pattern recognition) using similarity measures, like cosine similarity, cotangent similarity, and Dice similarity, and entropy measures.
